T 0 all whom it may concern Be it known that I, WALDOW F. MYERS, acitizen of the Jnited States, residing at Fostoria, in the county ofSeneca and State of Ohio, have invented new and useful Improvements inBolt-Locks, of which the following is a specification.

The present invention relates to improvements in bolt locks and residesin the construction, combination and arrangement of parts set forth inthe following specification and falling within the scope of the appendedclaims.

The drawings illustrate a satisfactory reduction of my improvementtopractice, and in said drawings: Figure 1 is a perspective viewillustrating my improvement in connection with a rail chair employed inconnecting two rail ends, Fig. 2' is a top plan View of the same, Fig. 3is a transverse sectional view on the line 33 of Fig. 2, Fig. 1 is asimilar sectional view on the line 1- 1 of Fig. 2, Fig. 5 is ahorizontal sectional view on the line 55 of Fig. 3, Fig. 6 is a detailperspective view illustrating the rails in position upon one member ofthe chair, preparatory to receiving the second member of the chair, Fig.7 is a view of the improvement illustrating the bolt locking capsremoved, Fig. 8 is a perspective view looking toward the underface ofone of the bolt caps, and Fig. 9 is a longitudinal sectional viewillustrating the slidable latch members provided upon the block andadapted to secure the block in position, Fig. 10 is an enlarged invertedperspective view of the block illustrated in Fig. 9, Fig. 11 is anenlarged sectional view showing the manner in which the sliding boltsare forced to within the recesses whenthe cap block is inserted over thehead of the bolt.

In the drawings my improved nut lock has been shown in connection with arail chair, the same being primarily adapted for use in connection withrail chairs, and in the following description, the same will be referredto in such connection. It is, however, to be understood that theimproved nut lock is not to be thus restricted in its useful employment.

In the drawings, the rails are indicated by the characters RR, while theties upon which the rails rest are indicated by the characters TT. Therails and ties are each of the ordinary construction, the base flangesof the rails, adjacent their ends, be-

vto raise the same flush with the upper faces of the ties. The base 3 isintegrally formed upon one of its longitudinal edges with a verticallyprojecting portion 4t which is formed with an inwardly extending angularflange 5, the space between the said flange and the base beingsuflicient to receive the base flanges of the rails R-R upon one of thesides of said rails. Disposed between the angular flan e and the base,and integrally connected therewith aswell as to the inner face of thevertical portion 4 are lugs 6, these lugs being adapted to engage withinthe notches 1 in the flanges of the rails. The upper flat face of thebase 3 to the opposite side thereof from its portions 1 and 5, is formedwith a plurality of spaced threaded depressionsor openings 7, two ofwhich being shown in the drawings.

The numeral 8 designates the removable member or side for the chair.This mem her 8 embodies an angular upper portion 9 which terminates in asubstantially vertical portion 10, the lower face of said portion 10being horizontally straight and being adapted to rest upon the flat faceof the base 3. The member 8 has its underface at its juncture with itsangular and vertical portions formed with lugs 11, the said lugs beingadapted to be received within the notches 1 upon this side of the railsR. The upper face of the member 8 is provided with spaced depressionsforming pockets 12, and the lower wall 13 of each of the said pockets isprovided with an aperture or opening 14 which is adapted, when the saidmember is arranged upon the base 3, to register with each of thethreaded openings 7 in the base. Passing through the openings 14, andengaging with the threads of the openings 7 are headed bolts 15, theheads of which being adapted to rest upon the lower walls of the pockets12- when the bolts are screwed entirely home. When the member 8 is thusconnected to'the base 3 its vertical portion 10 has its inner faceengaging with the longitudinal edges of the base flanges of the rails,while the angular portion 9 is forcibly brought into contact with thebase flanges of said rails. It may here be stated that the angularportions 5 and 9 of the chair have their inner longitudinal wallsvertically straight, and the said walls are adapted to tightly compressthe opposite faces of the webs of the rails at the juncture of the saidwebs with the base flanges of the rails.

In order to effectively retain the bolts 15 against accidental removalor unscrewing, incident to the vibration to which the rails aresubjected, I provide what I will term a cap block 16 for each of thepockets 12. These blocks are of a size and shape to be snugly receivedwithin the said pockets and to frictionally engage with the walls of thepockets. The blocks may, and preferably do, have their inner edges atthe lower portions thereof formed with extending tongues 17, the saidtongues preferably having their upper faces inclined or beveled fromtheir juncture with the cap blocks to their outer edges, and the innerlongitudinal walls provided by the pockets are formed with substantiallyV-shaped grooves 18 which are adapted to receive the tongues 17. The capblock may be made of malleable material, and each of said blocks isprovided upon its underface with a depression or channel 18, the wallsof which are inclined, so that the mouth of the opening 19 may be passedfreely over the upper portion of the head of the bolt, and upon beingforced downwardly to within the pocket will cause said walls to expandto force the sides of the block into tight frictional engagement withthe sides of the pocket 12. The outer edge of each of the blocks 17 isprovided with a depression 20 which is inclined to the lower wall ofsaid block, the said depression providing means whereby a pinch-bar maybe inserted between the block and the upper wall of the pocket to removethe block from the pocket. Other means may be employed. for securing thecap blocks within the pockets if desired, as for instance, and asillustrated in Fig. 9 of the drawings, the said block may be providedwith transverse openings which enter the depression 19, and arrangedwithin said openings are sliding bolts 21 which have beveled inner ends2:2, the said beveled ends being adapted to contact with the oppositefaces of the bolt to slide the same to force their opposite ends intogrooves 23 formed in the opposite side walls of the pocket.

From the above description, taken in connection with the accompanyingdrawings, the simplicity of the device as well as the advantages thereofwill, it is thought, be

perfectly apparent to those skilled in the art to which such inventionsappertain without further detailed description.

Having thus described the invention, what is claimed as new is:

1. A member comprising a base provided with threaded openings, a memberfor the base, said member having its upper face formed with pockets, andthe lower wall of the pockets having openings which are adapted toregister with the openings in the base, headed bolts passing through theopenings and engaging with the threaded openings in the base, a capmember for each of the pockets, each of said caps being provided with abolt head receiving depression which is adapted to engage with the headof the bolt to prevent the rotation of the bolt, and means for retainingthe cap members within the pockets.

2. A member including a base having threaded openings, a second memberadapted to be arranged over the base, said second member having itsupper face at its outer edge formed with pockets, and the lower walls ofthe pockets being formed with openings which are adapted to registerwith the openings in the base, a headed member passing through each ofthe openings and cooperating with the threaded openings in the base, acap member for each of the said pockets to close the same, each of saidcap members having a bolt head receiving depression, the cap membersbeing each formed with a tongue and one of the side walls of each of thepockets being provided with a groove for the reception of the tongue.

3. The combination with a member including a base having threadedopenings arranged adjacent one of its ends, a second member adapted toengage with the base and to overlie the portion thereof provided withthe openings, said second member being formed with pockets correspondingin number to the threaded openings of the base, and each of the saidpockets being provided with an opening which is adapted to register withthe corresponding threaded opening in the base, the inner walls of thepockets being provided with grooves, headed bolts passing through theopenings provided in the pockets and engaging with the threaded openingsin the base, a cap for each of the pockets, said cap having itsunderface provided with a bolt head receiving depression, said cap beingfurther provided upon its inner edge with tongues which are adapted tobe received within the grooves of the pocket when the caps are forcedinto the pockets and to have the walls of their depressions engage withthe heads of the bolts, and means for retaining the caps within thepockets.

4. The combination with a member having threaded openings, a secondmember adapted to be arranged upon the first member and to overlie theopenings, the second member being provided with pockets which registerwith the openings in the first memher, the second member being providedwith openings which enter the pockets, headed bolts passing throughthese openings and engaging the threaded openings in the first mentionedmember, the inner walls of the pockets being formed with grooves, theside walls of the pockets being also formed with depressions, a caphaving a bolt head receiving opening for each of the pockets, said caphaving its inner edge provided with tongues which are adapted to engagewith the grooves provided by the inner walls of the pockets, said caphaving transverse openings which enter their bolt head receivingopenings, slidable latch members within each of the said openings, saidlatch memin presence of two witnesses.
